I actually saw these bugs around for a couple of days before I realized they were alive. At first I thought they were plant matter; thorns or bristles. Even after I realized that they were insects, I assumed I was looking at castings of an insect that had molted.

It was confirmed this was a living insect when I saw this guys eating a leaf.

This was shot in foliage, 10 meters from the Indian Ocean in Mombasa, Kenya.
